Using the NEOS Server for Concorde

The user can currently choose between applying the exact algorithm and the
Lin-Kernighan heuristic (especially for large instances).
Concorde can be called with the authors'
QSopt LP solver
or
CPLEX.
This small
benchmark gives you an
impression of its performance with different LP solvers.
If Concorde terminates prematurely it may have run out of time or memory.
Either the fixed random seed 99 can be used or a variable one.
Users who submit via web submission (not email or XML-RPC) can further
choose to receive a PDF file plotting the optimal resp. final tour.
